RO2073A-6

Resonators Overview

The RO2073A-6 is a one-port surface-acoustic-wave (SAW) resonator manufactured by Murata Electronics. It operates at a nominal frequency of 315 MHz and is housed in a ceramic SM-2 package with four pins. The device offers a frequency tolerance of ±50 kHz and a stability of ±0.032 ppm. It features a low series resistance and complies with RoHS directives. The component is designed for surface-mount installation, providing quartz-like frequency stabilization for local oscillators.

Resonators Feature Summary

• Provides fundamental-mode frequency stabilization comparable to quartz
• Utilizes a surface-mount ceramic case for reliable integration
• Designed for low series resistance applications

Resonators Applications

• Automotive keyless entry transmitters
• AM transmitters operating under FCC Part 15 regulations
• Local oscillator circuits requiring stable reference frequencies

Resonators Procurement Notes

Verify the specific suffix against official Murata documentation to confirm exact electrical characteristics and packaging details. Ensure compatibility with automotive environmental standards if used in vehicle systems. Cross-reference the part number with current lifecycle status to confirm availability and active production status before finalizing procurement plans.

Resonators Selection Notes

Select this component for applications requiring precise 315 MHz stabilization in compact surface-mount designs. Consider the SM-2 package dimensions and thermal operating range when designing the PCB layout. Evaluate the low series resistance benefit for signal integrity in transmitter circuits compared to alternative resonator technologies.

Resonators Part Context

This part belongs to the RO2073A series of SAW resonators from Murata Electronics. The series is specifically engineered for radio frequency applications, offering a balance between performance and size. The RO2073A-6 variant targets the 315 MHz band, distinct from other variants that may operate at different frequencies within the same family.

Resonators Replacement Considerations

Consult official Murata substitution guides for verified alternatives. Generic cross-references may not match the specific SM-2 package or electrical tolerances required for certified automotive compliance.
